I will be the Tiger Woods and say I love all three

Like you, I started playing pinball at the end of the EM period, the last few years of Gottlieb EMs, the year or so of Williams EM's, So many classic games
Then to fall in love with the the new electronic games, those Gottieb sys1 with their big blue displays, the deep electric tones, all of them are great
Then about 1979, the desiners finally learn how to program, and with better sound boards pinball really takes off
Fast forward to the DMD, I do not know what was in the water at Bally/Williams during the days of WPC, but most of the games then seem to have an extra layer of fairy dust that makes so many of them fun to play
(the fairy dust sems to be missing though from WPC-95 games)
